Im trying to model the earth orbiting the sun using the Verlet method.

Id like to plot the results, animate them if possible

All I get is a graph with a line.

can anyone help me see where Im going wrong?

import matplotlib.pyplot as plt import matplotlib.patches as ptch import matplotlib.lines as lne import matplotlib.animation as ani import matplotlib from mpl_toolkits.mplot3d import Axes3D import numpy as np import matplotlib.pyplot as plt import scipy as sp #Gravitation is a conservative force such that E+T+V #The total energy of the system can be expressed as a pair of first order ordinary differential equations (ODE s)
